I've been mulling over selling my Detective Comics # 1 8.5 with an auction house. They're estimating an obscene amount for the comic. I purchased it in the 90's for 10k, they are projecting over 100k for it. Normally, I wouldn't, but with comics so high, I am concerned that the price, over time, will just go back to 10k or below. They also want me to list my Superman # 1 @ 7.5, Batman #1 8.5, Spiderman # 1 @ 9.4 and Amazing Fantasy 15 @ 5, but I am not too keen on selling those.
What would you guys suggest? I've been going back and forth in my mind for years on all of them. I also have others, but these are probably the most coveted. The insurance premiums have been going up as the values continue to climb too.
